Troubleshooting Confidential
Troubleshooting Confidential Host System MSB on board Host System MSB on board Hardware Issue Software Issue Unable to detect MSB by the host Able to detect MSB, Driver could install on the system completely
Hardware Troubleshooting Step1. Plug MSB, but system hangs. Unplug MSB, system works. (Check if the CPU ) Step2.Check MSB is fixed Step3. Wipe edge-board contact (gold finger) Step4. Change another card Confidential
Software Troubleshooting Error Code(Windows Device Manager) Collect the information and contact Moxa Confidential
Software Troubleshooting Compile error(Linux) Should install kernel-source in advance Still cant work, please collect the error massage and contact Moxa. Confidential
If install driver successfully, but still cant work. What Should I do? Confidential Use PComm Utility
Test Utilities-PComm What is Diagnostic Provide internal and external testing, such as IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD Multiport Serial Boards only When to use Diagnostic Driver Installation completed, then you want to check if MSB works functionally How to use Diagnostic Connect loopback terminator after COM ports and then run the diagnostics program.
